[mlpack-git] [mlpack/mlpack] Check if SortStruct provides any benefit. (#712)

[lozhnikov]

I wrote a simple test. With `-O3` `std::pair` is faster then `SortStruct`.
If `n=100M`:
```
SortStruct results:
sorted[0].n = 26200464
fill duration = 1620ms
sort duration = 17090ms
std::pair results:
sorted[0].n = 26200464
fill duration = 1597ms
sort duration = 12287ms
```
